Description

development of a number arranged on the switching disk 2

35 sheet 5 with an indication of the weekdays 6 and a respective hour division 7. 8 means a, for

The invention relates to a fine adjustment device switching disk 2 concentrically arranged adjustment

with the features according to the first part of the patent button with an intended speed of one revolution

Claim 1 rotation in 24 hours. The adjustment button 8 protrudes

Especially with time switches with a weekday 40 on. not shown in this figure, gear train A division on the circumference of a switching disk is one with the switching disk 2 in engagement. This makes it possible manual Time setting of the shell disc required, lent that the switching disc 2 werdie relatively finely adjusted it enables you to be on the switching disk on ice! den can, d. H. one full turn of the adjustment knob seventh of the total scope of the limited switching time in the direction of arrow 9, the switching disk 2 rotates borrowed day of the week simply and clearly by the hour - 45 sevenths of a turn, i.e. by one day, in the direction of the arrow and set to the desired time of day to the minute. 9. As a stationary reference point for the time setting allocate. The time-of-day position is to be used by a reference arrow 10 on the dial 5 Switching disk can be seen at a glance. Circuit board 1. An exact time setting of the switching disk

From DE-PS 11 76 737 a timer with a 2 is not guaranteed 24-hour switching disc and with a, with the ϊο According to the invention, an accurate time setting | The 12-hour hand mechanism coupled to the switching disc is achieved by pressing a | The setting of the pointer mechanism and the switching transparent disk 11 with time reference marks 12 in disk is made there by a on the rear wall which is arranged in a 24-hour division. The timer attached hand adjustment knob. This type of holding rotating, dial-like disk 11 can the setting is due to the large translation between 55 and manual operation on the frontal circumference the adjusting knob and the switching disk should be provided with a knurl 13, bend and awkward. The advantage of this arrangement is the relatively large one

From DE-OS 20 56 252 a timer with an ice part radius and the associated, simple, over-

In addition, there is a time of day due to the change of the tooth tips in each case further time reference marks

relatively rough time division can only be read imprecisely. In the case of the - represent between the time reference marks 12 and

With this time switch, the dial disc can correspond approximately to the 65 correct minute markers,

The invention is based on the object of a finely adjustable dial disc which disc 11 fulfills adjusting device of the type mentioned to function as a transparent cover glass for the switching

disk 2. To program the switching disk 2, the disk 11 can be removed from the setting button 8 will. For this purpose, locking elements 14 are provided on the disk 11, each of which is firmly bonded with the disk 11 are connected and can come into engagement with the adjustment knob 8.

In order to ensure a unique, time-related incorrect positioning of the disc 1 in the button 8, the locking elements 14 are spaced in their respective width different from each other. In addition, it is provided that a coaxially extending, concentrically pot-like arrangement on the disk 11, knurled-like internal toothing 15 can come into engagement with the conically extending front knurl 16 on the adjusting knob 8.

in FIG. 2 means 3 the front plate of the time switch with a housing 17.2 shows the switching disk, the is in engagement with a drive shaft 19 via a gear transmission 18. On the drive shaft 19, with a speed of one revolution in 24 hours

net On the adjustment knob 8 with a knurled head 16 is the disc 11 placed and by means of the locking elements 14 releasably fastened in a force-locking manner. The latching elements 14 engage there with latching teeth 20 in recesses 21 behind the adjustment knobs.

Instead of the described speed ratios of the switching disk 2 and the setting knob 8 can also other speeds or ratios occur between the switching disk 2 and the adjusting knob 8. Also is it is possible for the disc 11 to have a different shape and provided with symbols and reference marks other than those shown and described can be.
